Metallic receptacle



June 2, 1931. H. H. WARD METALLIC RECEPTAYCLE Filed June 18, 1928 form Patented June 2, 1931 PATENT GFFICE HUGH H. WARD, OF CHESTER, PENNSYLVANIA METALLIC RECEPTACLE Application filed June 18, 1928.

My invention is designed primarily to provide improved means for seating a bung in a receptacle made of sheet material and to avoid the necessity for a re-enforcing plate surrounding the bung hole or the use of other devices interposing obstruction to the complete drainage of the receptacle. In accordance with my invention, an integral sheet comprised in the body of the receptacle is so bent or fluted as to provide a secure seat for the bung and reenforcing ribs extending radially therefrom and aflording adequate resistance to strains incident to the driving or extraction of a bung.

My improvements are particularly applicable to barrels or other cask-like receptacles formed of sheet metal bent to form a curved body having heads permanently set in the ends thereof and a bung hole cut in the body between rolling hoops formed by protruding circumferential ribs thereon but the bung hole may be formed in a head instead of in the body. The body material adjacent to the bung hole is fluted to form radial, projecting or convex ribs whose inner ends terminate adjacent to the bung seat. The bung seat is preferably formed by bending or crimping the material immediately around the bung hole into an annular outwardly projecting ridge terminating in an inturned resilient flange or lip for engaging a driven bun the inner edge of the lip be- O7 ing preferably sli htly bent and lying approximately in the plane of the inner surface of the receptacle wall.

The characteristic features and advantages of my improvements will further appear from the following description and the accompanying drawings illustrating a preferred embodiment of my invention.

In the drawings, Fig. l is a top plan view of a cask or barrel embodying my improvements; Fig. 2 is an enlarged fragmentary sectional view taken through the bung hole; and Fig. 3 is an enlarged fragmentary plan View looking toward the bottom of the bung.

As illustrated in the drawings, my inven tion is applied to a barrel formed by rolling sheet metal into a cylindrical body 1 provided with rolling hoops 2 and having its Serial No. 286,151.

ends closed by heads 8,'the edgesof which are crimped over the ends of the body.

A bung hole 4 is formed in the curved wall of the body 1, preferably between the ribs or hoops 2, and a bung seat is formed of the metal immediately adjacent to the hole by pressing it outwardly into a convex or outwardly projecting annular ridge comprising a web 5 and a resilient lip 6 turned in from the web and spaced from the base thereof. The free edge of the lip is preferably bent slightly to form a projecting tongue or bead.

A substantially rectangular section of metal surounding the bung seat is reenforced and strengthened by having convex or outwardly projecting ribs 8 and 9 pressed therefrom with their inner ends adjacent to the periphery of the bung seat; the ribs extending radially from the bung hole and preferably being of different lengths.

A bung 10 may be driven into the bung hole without distortion of the receptacle and is firmly secured by the engagement of the lip 6 and particularly of the projecting bead forming the edge thereof.

Having described my invention, I claim:

A container comprising a cylindrical sheet metal body having annular rolling and reenforcing hoops bent outwardly therefrom,

said body having a bung hole formed in the curvel wall thereof between said hoops and being pressed outwardly into a convex ridge surrounding said bung hole and comprising a resilient lip with a projecting tongue thereon, a section of'the middle of the body surrounding the bung hole having outwardly projecting rims pressed therefrom with their outer ends adjacent to said hoops and their inner ends adjacent to the annular ridge, said ribs extending radially and being of different lengths, and a wooden bung engaged by the tongue of said resilient lip.

In witness whereof I have hereunto set my hand this 21st day of May, 1928.

HUGH. H. WARD.
